Here's a condensed guide from an opensuse site maybe you check through it and see you haven't missed a step

Quote

Open VirtualBox and click on the New button and then Next and then enter a name for your virtual machine.Then select the correct Operating System type and the Version from the respective drop down menus and then Next.Select the amount of memory that will be allocated to the guest OS.Warning Leave a sufficient amount for host OS itselfSelect Create new hard disk and click next, a new wizard will pop up.Follow the guide and select either a Dynamically expanding storage or a Fixed-size storageSelect the initial size of it. Then click on the Finish button.Click on the Next button and then the Finish button.Select your newly created virtual machine in the VirtualBox main interface and then click on Start.The "First Run Wizard" will pop up.Tell VirtualBox which ISO image file is to be used by selecting ISO Image File and use "Virtual Media Manager" to add your ISO image.The virtual machine will now boot from the image and you should proceed with the OS installation.

Good Luck

If you can keep your head while all around are losing theirs, then you're not quite grasping the situation

So.... Youíre saying the one I'm using is one of the two that is the better of the three?

Erm .. NO, I'm most definitely not saying that .. I'm just pointing out there are certain usage cases where KVM may not be an option, and there's certainly going to be more "newb" style tutorials available for VirtualBox and VMWare.(though there's probably better "technical" documentation for KVM)

In Linux, KVM is probably going to be "best", if by "best" you mean the most tightly integrated and efficient .. hell, as it's part of the Linux kernel, you already have the important components installed (think about it .. KVM = Kernel-based Virtual Machine)http://www.linux-kvm.org/page/Main_Page

When I say "KVM", KVM is actually an extension for QEMU, and QEMU does *not* need hardware acceleration. So, if you run the "KVM" package (which is really QEMU with the KVM extension) on really old hardware (!) it just means it'll run slower (just like Virtualbox!) , but if you have something a little more modern, KVM will kick in and give you 20x the performance.

AFAIK as a heavy KVM/QEMU user and a casual Virtualbox user I see;

a. KVM is a part of Linux and hence completely free, with all features in-tact, there is no commercial option.b. Virtualbox is a commercial product with a cut-down Open Source variant .. you get to a point where you want an advanced feature that may be available in KVM for example, then you get to pay.c. KVM is quicker and more stable than Virtualbox, and far more integrated as it's a part of the standard Kernel.d. Virtualbox is produced by the Evil Empire MK III, so IMHO you may as well be using a M$ product (!)

Which brings me back to "I'm failing to understand ..." ??

Also, SPICE is available on newer builds which gives you REALLY quick video on the console, not tried it myself but apparently it's good enough to watch movies (when run on a GUI inside the VM). Not sure whether Virtualbox has SPICE support?

.. given the current Sun, Java, MySQL and Open Office fiasco's , would you trust them to do anything right ??
